Galileo described the concept of motion relativity--motion with respect to a reference frame--in 1632. He noted that a person below deck would be unable to discern whether the boat was moving. Embryologists, while recognizing that embryonic tissues undergo large-scale deformations, have failed to account for relative motion when analyzing cell motility data. A century of scientific articles has...

Can we know that nothing is in itself both thinking and spatially extended?1 This was among the most central and divisive philosophical issues of the early modern period, one with obvious relevance not only to the theoretical understanding of mind and matter, but also to the practical prospects for immortality and, with it, divine sanctions for morality. While many important philosophers—includ...

OBJECTIVE To investigate the surface morphology, structure, elemental composition, and key mechanical properties of various sizes and tempers of Australian wires. MATERIALS AND METHODS Three types of Australian wire were used: 0.016'' regular, 0.018'' regular+, and 0.018'' special+ (A.J. Wilcock, Whittlesea, Victoria, Australia). Each type of wire was subjected to scanning electron microscopy...

Site-directed mutagenesis has been used to examine the function of a highly conserved aromatic residue, alpha Trp43, in the light-harvesting 1 antenna of the photosynthetic bacterium Rhodobacter sphaeroides. In this antenna alpha Trp43 is thought to be located near the putative binding site for bacteriochlorophyll; in this work it was changed to both Tyr and Phe, and in each case the main near-...

This essay draws upon the final report of the National Commission on the Cost of Higher Education (1998), Ehrenberg (2000), and King (1999) to explore (a) the cost of higher education at selective private colleges and universities, (b) public concern about the rising costs of higher education, and (c) the shift in financial aid policy from access to affordability. It also discusses implications...

Water density fluctuations are an important statistical mechanical observable that is related to many-body correlations, as well as hydrophobic hydration and interactions. Local water density fluctuations at a solid-water surface have also been proposed as a measure of it's hydrophobicity. These fluctuations can be quantified by calculating the probability, P(v)(N), of observing N waters in a p...

A new species of entomopathogenic nematode (EPN) named Steinernema balochiense n. sp. belonging to the family Steinernematidae was isolated from Psidium guajava L., rhizophere soil samples of Balochistan, Pakistan. This new species belongs to the carpocapsae group. The new species can be separated from other described species by morphological and morphometrics characteristics as well as DNA seq...

Evaluation of: Gattringer T, Ferrari J, Knoflach M et al. Sex-related differences of acute stroke unit care results from an Austrian stroke unit registry. Stroke 45, 1632-1638 (2014). The authors analyzed data from 47,209 patients diagnosed with ischemic stroke or transient ischemic attack from January 2005 to December 2012. In this study, epidemiological data, stroke type, diagnostics and clin...

Past slope instabilities at Quindici (one of the five towns of Campania that was hit by catastrophic landslides on 5 May 1998) and in the Lauro Valley are investigated to improve the understanding of the landslide history in the area, as a mandatory step for the evaluation of the landslide hazard. The research was performed by combining information on past slope instabilities from both historic...
